About this study
This is an international phase III trial, with a Bayesian design, incorporating two sequential randomisations. It efficiently examines a series of questions that routinely arise in the sequencing of treatment. The study design has evolved from lengthy international consultation that has enabled us to build consensus over which questions arise from current knowledge and practice. It will enable potential randomisation for the majority of patients with inguinal lymph node metastases and will provide data to inform future clinical decisions.
InPACT-neoadjuvant patients are stratified by disease burden as assessed by radiological criteria. Treatment options are then defined according to the disease burden strata. Treatment is allocated by randomisation. Patients may be allocated to one of three initial treatments:

- standard surgery (ILND); B. neoadjuvant chemotherapy followed by standard surgery (ILND); or C. neoadjuvant chemoradiotherapy followed by standard surgery (ILND).
After ILND, patients are defined as being at low or high risk of recurrence based on histological interpretation of the ILND specimen. Patients at high risk of relapse are eligible for InPACT-pelvis, where they are randomised to either:
- prophylactic PLND Q. no prophylactic PLND
- Being tested
- ILND - Inguinal Lymph Node Dissection, Paclitaxel, Ifosfamide, Cisplatin, Intensity modulated radiation treatment (IMRT)

What is being measured
The primary outcome is the main question the study is designed to answer.
Overall survival
The primary outcome measure that will be measured for all trial patients is survival time. This is defined in whole days as the time from the date of randomisation to the date of death from any cause; for those who have not been reported as dead at the time of analysis, the survival time will be censored at the date of last follow-up.
Measured: up to 5 years
Secondary outcomes (10)
Disease specific survival time
Disease-specific survival time which is defined in whole days as the time from the date of randomisation to the date of death specifically from disease; for those who have not been reported as dead at the time of analysis, the survival time will be censored at the date of last follow-up and for those whose death is reported as non-disease specific then the survival time will be censored at date of death.
Measured: up to 5 years
Number of patients experience a grade 3 or 4 toxicity
Measured: up to 5 years
Disease-free survival time
Disease-free survival time (DFST) which is defined in whole days as the time from date of randomisation to the date of either locoregional recurrence, distant metastasis or death from disease, whichever occurs first; for those who have not been reported as experiencing any of these events, the DFST will be censored at the date last known to be alive and free of disease or date of non-disease-specific death. A supplementary exploratory outcome measure will also be calculated taking date of penectomy as the origin rather than date of randomisation.
Subsidiary outcome measures will be
- locoregional recurrence free survival time (LRFST).
- distant metastases free survival time (DMFST).
- A supplementary exploratory outcome measure will also be calculated taking date of penectomy as the origin for all these outcome measures rather than date of randomisation.
Measured: up to 5 years
Occurrence of surgical complication
Measured: up to 5 years
Is it possible to achieve pathological nodal assessment after chemotherapy
Feasibility of pathological nodal assessment after chemotherapy which is recorded as whether or not it was possible to achieve a pathological nodal assessment after chemotherapy.
Measured: 12 weeks
Quality of life
Measured using the EORTC-QLQC30 and Lymphodema-QL
Measured: Baseline, 3, 6, 9, 12, 18, 24 and 36 months
Occurrence of Pathological complete remission
Measured for all patients in InPACT-neoadjuvant:
Absolute absence of disease on histological examination
Measured: Time to complete remission after randomisation
Operability
Measured for all trial patients in InPACT-neoadjuvant. Operability which will be recorded as whether or not the planned inguinal node dissection was undertaken and the reasons if it did not occur.
Measured: 2-6 weeks
Occurrence of Lower limb/scrotal oedema
Occurrence of Lower limb/scrotal oedema which is recorded as whether or not the patient experiences a lower limb or scrotal oedema
Measured: up to 5 years
On-schedule delivery of neoadjuvant therapy
Feasibility of on-schedule delivery of neoadjuvant therapy
Measured: After randomisation up to 12 weeks

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing ILND - Inguinal Lymph Node Dissection, Paclitaxel and Ifosfamide in people with Squamous Cell Carcinoma of the Penis, Usual Type, run by Institute of Cancer Research, United Kingdom at 17 sites in 2 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 31 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 17 sites in United States, United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Overall survival (time frame: up to 5 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Aug 2026.
